Temporal Pattern Analysis

Daily and Hourly Distribution

Time of Day Patterns:

  • Morning Peak (7-9 AM): Coincides with work/school commute
  • Evening Peak (4-6 PM): Shows highest accident frequency
  • Night Hours (11 PM-4 AM): Lower frequency but higher severity
  • Mid-day (10 AM-3 PM): Moderate but steady accident rates

Weekly Pattern Analysis

Weekly Distribution:

  • Weekdays show distinct rush-hour patterns
  • Friday evenings have notably higher accident rates
  • Weekend patterns differ with:
    • Later morning peak times
    • More evenly distributed afternoon accidents
    • Extended evening accident periods
  • Early morning hours (2-5 AM) consistently show lowest rates across all days

Critical Time Periods:

Weekday Peaks

  • Morning: 7:00-9:00 AM
  • Evening: 4:00-6:30 PM

Weekend Patterns

  • Mid-morning: 10:00 AM-12:00 PM
  • Afternoon: 2:00-6:00 PM

High Severity Times

  • Night: 11:00 PM-2:00 AM
  • Early Morning: 4:00-6:00 AM

Temporal Pattern Recommendations:

  • Enhance traffic management during identified peak hours
  • Implement specific weekend safety measures
  • Increase visibility and safety measures during night hours
  • Develop time-specific intervention strategies

Severity Analysis

Severity Trends:

  • Overall decrease in accident numbers from 2015 to 2018
  • Slight accidents show the most significant reduction
  • Fatal accidents remain relatively constant despite overall reductions
  • Serious accidents show slight proportional increase

Weather Impact Analysis

Weather-Related Findings:

  • Clear weather accounts for majority of accidents due to higher traffic volume
  • Rain increases accident likelihood but not necessarily severity
  • Snow and ice conditions show fewer but more severe accidents
  • Poor visibility conditions correlate with higher severity rates

Vehicle Type Analysis

Vehicle-Related Insights:

  • Cars are involved in approximately 80% of all accidents
  • Two-wheeled vehicles show higher severity rates per incident
  • Heavy goods vehicles show lower frequency but higher severity
  • Vehicle type influences accident severity significantly

Casualty Analysis

Casualty Patterns:

  • Young adults (18-25) show higher involvement rates
  • Elderly casualties (65+) show higher severity rates when involved
  • Gender differences are evident across age groups
  • Pedestrian casualties show distinct patterns from vehicle occupants

Key Findings and Recommendations

Primary Recommendations:

  • Implement targeted safety measures during peak hours
  • Enhance safety education for high-risk age groups
  • Develop weather-specific traffic management strategies
  • Focus on vulnerable road user protection
  • Improve road design at high-risk locations

Future Research Directions:

  • Detailed analysis of specific vehicle type patterns
  • Investigation of intervention effectiveness
  • Study of behavioral factors in accidents
  • Analysis of geographical patterns
